CORPORATION or nnnawanaHONGOMRUS'IIBLE GHIiORINLTED HYDROGARBON AND PROCESS OF PRODUCING THESAME Application filed March 11, 1927.. Serial No. 174,842.

The invention relates to non-combustible material comprising ahydrocarbon united with chlorine useful as a cleaner or solvent.

It is an object of the invention to prepare commercial gasoline fortreatment and to then treat the prepared asoline so as to relace certainof the hyd rogen atoms of hycarbon with chlorine.

It is a further object of the invention to 3 produce a non-combustiblesubstance of the character described of use as a cleaner, which may beused instead of turpentine as a solvent in the preparation of paints,varnishes and the like. 1

35 Further objects of the invention will ap- -pear from the followingdescription when read in connection with the accompanying drawing inwhich the figure is a diagrammatic representation of apparatus forcarrying out the process of the invention.

Commercial gasoline as supplied to the trade is found to comprisehydrocarbon of which a representative formula is C H in combination witha variety of heavy hydrocarbons in the nature of lubricating oils. Inattempts to treat gasolines for the present purpose as heretofore knownthe difiiculty has been found that the treatment has failed in the caseof some of the gasolines upon the market because of the variation in theheavy oils contained therein.

According to the present invention the com mercial gasoline is firstthoroughly agitated with a solution of sodium hydroxide which has theresult of saponifying the heavy oils which saponified material settlesto the bottom of the receptacle from which the purified soline may bedecanted or drawn ofi.

The thus treated gasoline is introduced 7 into a-receptacle such asindicated at 10 in the drawing as by a pipe 11 and the receptacle maythen be closed as by means of valve 12. v

Before closure of the receptacle, there is introducedinto the same perone hundred galions of purified gasoline, five gallons ofperchlormethane, one gallon of aqua ammonia, andten pounds of eitheraluminum or ferric chloride.

The mixture of the last named substances ammonia and chloride acting asa catalyst,

certain of the hydrogen atoms of the hydrocarbon will be displaced bychlorine atoms, said hydrogen atoms then combining with other chlorineatoms to form hydrochloric acid with production of heat as a result ofthe chemical action and the hydrochloric acid will escape in a gaseouscondition.

The gaseous hydrochloric acid is led from the receptacle 10 as through apipe 16 and is passed through a condenser 17 through which a coolingagent is led about the pipe 16 as by means of pipes 18, 19. The thuscooled gaseous hydrochloric acid is then collected in a receptacle 20,by bubbling through water 23. The reaction is carried on until thespecific gravity of the material under treatment reaches a point ofsubstantially 1.32. The treated material is then led from therecepta2cle 10 through a lead pipe 21 to a receptacle To neutralize thereaction of the treated material, the material in the receptacle 22 orin any convenient manner is again washed with sodium hydroxide afterwhichrthe material is ready for use.

Receptacle 10 is preferably a lead lined chamber and the same materialis desirably used for pipe 16 and receptacle 20.

The material thus provided is found to be a very valuable cleaning agentfor clothes or fabrics and will dissolve greases of all char acter,paint and the like without injury to the color of the fabric, its effectupon the color ,being that of a mordant. Using a gasoline having arepresentative formula such as (3 H the representative formula of theproduct is found to be C H Cl v 7 Also the material is found to-beabsolutely non-inflammable and non-explosive.

, Because of its solvent ualities, the material may also be used in pace ofturpentine in preparation of paints and varnishes since it readilyvaporizes and is an excellent solvent for the material of which paintsand varnishes are manufactured.

The heavy ends removed from the asoline m by the first treatment withcaustic a1 ali are recovered and utilized for lubricating puroses andmay be used in their saponified contion.

Minor changes may be made in the steps of the process or quantities ofthe material used within the scope of the appended claimswithout'departing from the sp rit of the invention. I claim:

' go 1. The method of chlorinating gasoline which comprises treatin thegasoline to remove heavy ends, bub ling chlorine gas through the thustreated gasoline in the presence of perchlormethane, ammonia and a ametallic chloride.

2. The method of chlorinating asoline which comprises removing heavy ens from the gasoline by treatment with a solution of caustic alkalinemetal hydroxide, bubbling a0 chlorine gas through the purified gasolinein the resence of'perchlormethane, aqua ammonla and ferric chloride, andneutralizing the reaction of the thus chlorinated product by treatmentwith a solution of an alkaline '35 metal hydroxide.

3. The method of reparing a lubricant and a chlorinated hy rocarbonwhich com- 4 prises treating commercial gasoline with v a solution ofcaustic alkaline-metal hydroxide 40 to remove the heavy ends, recoveringthe heav ends in sa onified condition for use as a ubricant, bub lingchlorine gas through the thus treated gasoline in the presence ofperchlormethane, ammonia and a metallic chloride.

4. A mixture of chlorinated hydrocarbons havin representative formulaesuch as C H, 1-, with a neutral reaction.

In testimony whereof I afiix my si ature.
